Solid-Phase Synthesis of Oligo(phenylene ethynylene) Rotaxanes

摘要

Solid-phase synthesis is an attractive method for the construction of complex linear oligomers,such as peptides and oligonucleotides,because it provides complete control of the oligomer length and sequence while avoiding the need for purification after every growth step.This strategy has been exploited to synthesize pi-conjugated oligomers for optoelectronic applications,such as oligo(phenylene ethynylene)s (OPEs),oligothiophenes,and oligo(phenylenetriacety-lene)s.
